Description

Field of the invention

The invention relates to a folding box for packaging at least one object or a piece of jewelry or watches, said folding case being storable flat in a base plane defined by a longitudinal direction and by a direction transverse, said box comprising a foldable internal container formed by a first band closed on itself and forming a first foldable deformable prism between a flat position and an extended position where said first deformable prism is open at two opposite ends in a parallel direction in said transverse direction, said inner container having an operating surface which is integral with a second band extending in said transverse direction, and said second band being integral, at a separate bottom of said internal container, with a outer casing formed by a third band extending in said longitudinal direction tudinal and deformable between a storage position flat in said plane and a folded position where said third band is closed on itself and arranged to surround said inner container, which inner container is foldable around a fold that includes said second band between said maneuvering surface and said bottom, when said inner container is in an extended position and is in a folded position, resting on an upper surface of said bottom so that one of said outer openings of said inner container is closed by said bottom.

The invention relates to the field of packaging objects, and more particularly the field of boxes, or packaging transport or storage for timepieces or jewelry.

Background of the invention

The packaging of objects, including jewelry or timepieces requires the support of a good protection of the object.

Usually used padding for this purpose, but the pad is generally not versatile, or it protects the object badly.

It is preferable to remove the object from the walls of the box or the box, to protect it from shocks and aggression that undergoes this box.

In the particular case of jewelry or timepieces of substantially toric shape, it is known to use cushions on which these objects are threaded, however it is necessary to maintain the cushion itself, by embedding in a cavity, or padding it on both sides.

Good packaging is relatively complex, has several components, and its cost can be high compared to that of the object to be protected.

The production of moderate production cost packaging designed to provide optimum protection of the timepiece or jewelry, is therefore a permanent concern of the watchmaking and jewelery manufacturers, especially as the cases or Cases are kept throughout the life of the object. It is advisable, also, to respect a certain classicism of presentation, and to propose a purified packaging, and worthy of the object which it contains.

A good solution for the protection problem lies in a double packaging, with the object enclosed in a first box itself locked in a second. The protection of the object is assured, but the double packaging is expensive, and the user does not immediately access the object.

Cases with hinged covers are also quite expensive solutions.

There are packaging from cardboard boxes, which meet the need for protection with the choice of a material of sufficient thickness. They also have the advantage of a low cost, and can receive all types of decorations. Fully assembled cartons consume storage space. The advantage of folding carton is a flat storage, which saves space, combined with a lower cost than fully assembled cartonnages, because of the economy of the assembly labor. But it is often difficult to keep them in the unfolded position, except using tabs or tabs unsightly and deteriorating over time after a number of manipulations, or to make a reduction in the available interior volume to accommodate creases or double partitions, or the like, required by the kinematics of folding and deployment.

A patent application FR 2 678 583 in the name of EDITH HERMAN describes a packaging box forming a display unit from a single blank with a folding system around a square bottom. This simple box however has bellows occupying part of the interior volume.

A patent application EP 1 228 971 in the name of KRAFFT GOEBEL has a shockproof housing where the product to be protected is maintained by Z-flaps having a certain elasticity.

The patent EP 0 489 606 B1 in the name of HRICOVINI EVA describes a family of cardboard boxes closed by partially open tetrahedrons folded over the insertion opening of the content.

A FR 2 665 881 A1 in the name of RICHEZ NICOLE describes a folding package cooperating with a folding display in the form of two independent parts, which is a usual configuration for a box or a jewelry box. US 5 873 457 A in the name of MADWED MARK discloses the maintenance of a toric object such as a watch around a cross member inserted into two opposite openings of a box with lid hinged box forming, this cross is operated at the way of a drawer for, as appropriate, to secure or release the watch from its case.

A document US 2006 0 191 801 in the name of JACK HERZOG describes, in a similar manner, a hinged lid box, having a hollow compartment for receiving a watch, this watch being secured or not to the box by a through elastic pin.

Known folding cases all have the same propensity to close, and can not maintain the geometry at right angles without the presence of a false bottom or wedging.

In short, there are few cases low cost, storable flat, and able to offer good protection to a timepiece or similar, while having a neat aesthetic without salient or fragile elements.

The patent application EP 2 602 205 in the name of TISSOT SA proposes a folding case, storable flat, with two prismatic structures preassembled and foldable on one another for the construction of the deployed case, which is stiffened in position by intrinsic struts and / or a movable crosshead.
